Minor.

Fix setDefaultRotation() when changing an object; do it at exactly the right time when the 'old' object has already disappeared, but the new hasn't been attached to the Nodee yet.

Include the info about 'numFaces' of a puzzle in the jsons.
Based on this, and the recently introduced 'DEFAULT_ROTs' to the basic Shape classes, rotate each object in the Config so it looks attractive.

Move info about the default rotation of the 4 basic shapes of puzzles form the 'Creator' app to the Shape classes.

'Simple' and 'Nice' meshes: fix Ivy.

'Simple' and 'Nice' meshes: fix Rex.

Introduce 'Simple' and 'Nice' meshes.

In the 'magic' app, ObjectType is now only used in RubikObject and RubikObjectList classes and nowhere else.
This is a major step towards being able to download objects from an online repository.

Progress replacing the enum ObjetType with the class RubikObjectList.

Fix projection matrix with which the puzzles get rendered: make it independent of the aspect ratio of the underlying surface.
